In Figure 11, the numeral 1 generallly designates a corn and cotton planter 'and fertlli-zer distributor of a Well known type of construction. The pl'ante-r and fertilizer distributor has a frame m'ovably supported at its forward end on a ground Wheel 2,

the frame including a :pair "of "rearwar'clly 'di'vergentside beams 3. The frame of the fplanter and' fer't ilizer distributor of course end of "the frame for -coverih-g the dropped Su-Ch 'rear supporting V and covering means are not shown in' the two standards 4 and through alined trans verse openings in the rearward end portions of the side beams 3. Nuts 7 are screwed on the outer ends of the rod 6 against the outer faces of the side beams 3. The respective side blade supporting standards 4 are swinglable on the cross rod 6 and are held against the inner faces of the side beams 3 of a rear cross bar 8. The rear cross bar 8 is best seen in Figure 4 and has upturned end portions 8 provided with alined openings 8 and also is bent upwardly substantially into inverted U- shape intermediate its length as indicatedat 8, the side members of the portion 8 having alined openings as at 8 which also are in alinement with the openings8 The cross rod 6 extends through the openings 8"-8 8 so that the cross bar 8 will be supported on the cross rod 6 and the upturned end portions 8 will be in contact with the inner faces of the standards 4 and will hold said standards against the inner faces of the side beams 3. The standards 4 are arranged on the cross rod 6 with-the concavely curved facesthereof at the front, and each standard 4 is provided with an opening 9 adjacent to its lower end for the reception of a bolt 10 for securing a side cultivating blade 11 or 12 on the lower end portion of the standards 4 at the front thereof, the blade 11 being secured to one of the standards 4 and the blade 12 being secured to the other standard 4.

The standards 4 are held against swinging about the axis of the cross rod 6from any onecof a plurality of adjusted positions by means of bolts 13 each of which extends through a transverse opening in a side beam 3, through one of a plurality of vertically spaced transverse openings 14 in the extreme upper end portion of the adjacent standard 4 and through an opening 15 in the adjacent downturned end portion16 of a front cross bar 16, the bolts 13 having the free end portions thereof engaged by nuts-17. The standards 4 thus may be releasably held in any one of a plurality of adjusted positions about the axisof the cross rod 6 and the distance of the 'lowerends of the blades on the standards4 to the side beams 3 can be varied within limits. In the embodiment of the invention shown, each of the standards 4 is provided with only two of the openings 14, but it'is obvious that a greater number of such openings can be provided, if desired.

of the rear cross bar and is connected with the latter by means of the cross rod 6 which extends through an opening in the center beam. The center beam 18 thus is supported midway between the side beams 3 and extends rearwardly beyond the rearward ends of the side beams. This center beam 18 carries a third blade supporting standard indicated at 19. The standard 19 iscurved to have the same general shape as the side blade supporting standards 4, but is slotted longitudinally from its upper end nearly to its lower end as indicated at 20. The center beam 18 is received in the upper end portion of the slot 20. and the standard 19 is pivotally attached to the center beam 18 by a transverse pivot bolt 21. The pivot bolt 21 extends through the standard 19 at a slight distance from the upper end of the latter, and through the center beam 18 at a slight distance from its rearward end. .The stand ard 19 is held against swinging about the axis of the pivot bolt 21 from anyone of a plurality of adjusted positions by a bolt 22 which extends through any selected pair of alined transverse openings 23 in the furcations of the slotted standard 19 and through a transverse opening '24 in the center beam 18, there being a plurality of vertically spaced openings 23 in each furcation of the slotted beam 19. The distance from the lower end of a breakerand distributor blade 25 which is secured on the lower end portion of the standard 19 by a bolt 26, to the center beam 18 thus may be varied within limits by engaging the bolt 22 with openings 23 at different levels on the upper end aortions of the furcations of the slotted standard 19.

The standards 19 and the rear end portion of the Center beam 18 are stayed to'the rear cross bar 8 and to the cross rod 6 by brace bars 27, each of which has an opentions with the cross bar 6 and being held on v the cross bar 6 against the inner faces of the upturned end portions 8 at opposite ends of the cross bar 8 by spacing and housing sleeves 28 which surround the portions of the cross bar 6 betweenthe upturned end portion 8 and the inverted U-shaped middle V nmate portion8 of thecross bars. "A- well "braced and stable construction thus is ,providedffor supporting the side standards); -*and the middle standard 19 which "is disposed .rearwardly of the'side standards -and at approximately -the same distance from each ot'thestandards i. V

"The attachment, also comprises means whereby the standards 4 and "19 and "the hereinbefore described means by --wh-ich the standards are "supported can be adjusted vertically within limits with respectto'the surface of "the earth "for purpose, as for example to-permit removal or replacement of theblade's on the standards or to vary the depth which the blades -'will penetrate in the soil, "-Sueh adjusting means comprises a slide foot 29 Whichis secured by a pair of clamping plates'30 and f as 'tening devioes"31*to"the lower--end portion "of aslide'foot'supporting standard 32. The

latter extends Vertically between the furc'ations ofthe slotted standard "'19-and;-is held against moving rearward 'or forward with respect to the standard 19 by a-guide bdlt or'pin 33 trwhichextends 'between the "furcations of the-standard 19 through 'a '"vertical guide "slot 34 in the slidefoot-supporting standard -32.- The-standard 32 is retained against swinging about the axis of the guide bolt-'33 by a" guide strap which is :shown as being "substantially U-"shaped andas having "arm straddling the re'arward end porti'on'of the'center beam 18and being secured to the latter by "transverse fastening elements '36so that a=space is provided between the we'b 'of the-1g1'iide' 35 'and the rearwardend'of the eenter 'beam through which the .upper end portion of the standard '32 may be sli'd. Th'e stand-ard 32 is held in vertically adjusted position with respect to the center beam- 18 by a. latch bolt '37 which slides on the upper sideof the center standard' t-hrough alatch bnlt guide 38 which is secured to the center :beam

'18 by the fastening devices" 36, thellatch bolt 37 being urged axiallyrearward by aniac- "tuating spring 39 to pos'itionito engage with =any "one of plurality :of vertically spaced matches l-O in 'th'e front edge 'of 'the standard 32. The spring I39=is housed iin a' substantially --U-shaped member iil havingzarms straddling the center beam '18 :and "secured to the latter by bolts 42, t'he web portion "of fhespring housing41 'being spaced from the upper edge of "the center beam 18 for the-reception of the 'spring '39 and also for the reception otthe rearward end portion of the l-zuieh'bolt"37 the web-of"the housing member 41 having *a pendent stop projection "42 atits 'forward end against which "the "forwarden'd of the spring 39 reacts.

*From the foregoing description of the V wa-rions parts of the 'device,theoperation of as. fairly vertical median line of the blade so'that the blade 25 is adapted not only toeut intolthe soil'butto deflect the loose surfaeesoil re'arwardl'yand outwardly. The side blades 1 1 and 12eXtend laterally 'outward from ithe sidestandards "4: and are curved "and other wise fashioned to not only cut intoflthe soil but to "deflect loose soil-outwardly 'from' the standards or in other,-worids, toward the rows between which'the attachment isdraWn.

The 'soil containing the peas, fertilizer or the like therefore will be well broken up and distributed throughoutthespacebetween the rows at the same time such ipeas .or fertilizer are dropped-between the rows. A considerable economy in the time-sand labor and equipment required; for the plant- 'ingiof the peas or the application andedistribution of fertilizer betweenzadj acent row-s therefore will be eifectedwhen the improved attachment is applied :to a a planter in .the manner described initheiforegoing;
